JTO all whom t mag/Concern: g

Be it known that LBENJAMINL. CHAM- Y BENAivrINfLooKHAuT .errar/irene, or Elmira, coronare. 'f

" L Buns, a citizen ofthe UnitedStates, .and a residentA 013 Fruita, in the county of MesaV andf State of Colorado,y have invented a new and useful Improvement inv Attachments f for vFlushing-Tanks, of which v"the followlng is :a specification. 4

"its obj ectV tol provide v av connection between yMyinvention is an improvement in attachments'for flushingtanks, and has for la flushingy tank and its supply pipe for absorbing and veliminating thechattering, jarring noises incidentft'ofthe refilling of suchtank after lushing. .Y

'In the drawings: Figure 1' is Va perspective viewvwith the'improved pipe. in place, Fig, 2 is a longitudinal vertical section ofthe pipe,`and Fig. 3 is asection on the line 3f3 ofFig. 2.

The present embodiment of the'invention `@is shown in connection withV theflushing tank l of a closet bowl 2, the said tank and bowlbeing of any usual orkdesiredconstruction. In the present instance the tank is "operated to lush thebowlby Vmeans of a f leverr3,l which extends through a verticaly slot .4 in the end of thetanlgand a grip or handle 5 Vis connected to the outer end of the'leverby means of a flexible member 6.

The improvement is` arrangedbetween the water supply pipe 7 for the tank and the tank, and-connects the supply pipe With'the tank. The supply pipe 7 enters through the floor 8 in the usual Amanner and the tank 1 is connected` to the bowl by the usual connection-9. v f y The improvement vcomprises a tubular casing or pipe 10 -lol rubber or the like,

preferably asection of heavy rubber tubing.

" closely within the lowerend ofthe tubular Fig 2, thatthe` ferrule isv corrugated ancasing, and a sleeve. or errule 13 encircles 'the casing at the nut to clamp the casing to the nut vin a water tight joint.

VIt will be noted from anfinspection of nularly to provide a better joint. The upper end' of the nut 11 is 'recessed or cupped as indicated atV 14, andthe upperfend of',` the supply pipe-7 extends well:up,into the cup or recess Vbut not sohigh as the upper1 ATTAC:Hivrulv'rA Yrola ELsiinvTANKs.,

ing. 'It will bevf noted from an inspection,"

ofFig. 2 that the nut 17fis.annul'arlyfrev duced at its lowerend Vto lit within theytubularlcasing, as'indicated vat 19, .and the up-- per end of the tubular casing bears against f an annular shoulder 2 0, formed between the body of the nut andthe reduced portion.

externally threaded at its upper end` and above the shoulder 20.

The upper end of the nut 13 is cupped or recessed asfindicated at 21, and the nut isy A packing 22 is 1y arranged within the recessor depression'85 21, anda cap 23y is threaded on tothe upper end of the nut, the cap coperating with i the'nutto compress the packing 22 around the pipe 15 inforder to make a tightjoint. The lower endoi the pipe 15 is closed by a hoodv or shield to vprevent the direct passage of the water from the supply p ipe toV the inlet pipe, said :shield or hood being 1n theorm of aV cap 24, the `said cap being locked upon Vthe lower end by Ameans of Vstruckup lugs 25 at the inner surface vof the cap which engage notches-in the pipe.`

The cap and the pipe areprovided lwith registering radial openings 26,1011 permit-` v ting the entrance of water to the pipe. VThe ,lowerfend of the pipe is-however,vclosed by the' cap so thatthe water cannot llow directly from the supply pipe'7 into the adjacent end of the pipe 15.. The lannular chamber. ,formed between the pipe 15 and the tubular casing 10 is the air chamber andV Jforms a cushion to absorb the noise vand j ar usually found Vin closets of this` character.

It will be `noted from` an inspection of Fig. 3, that the ferrules of Vsleeves 13 and 18.2are releasable.V These sleeves are split Q8 at the split. Bolts 29 are passed through registering openings in the flanges, and nuts 30 are threaded on to the bolts to clamp the flanges together. One of the flanges in the present instance, the flange 2S, has an outwardly extending rib 3l, forengaging the adjacent nuts to prevent rotation thereof.

The tubular casing l0 may be removed merely by releasing the fel-rules 13 and 1S. The cup or recess la'- in the lower end is for the purpose ofpreventing the entrance of sediment into the open .upper end of the supply pipe 7. Any sediment that may enter will fall into this recess, and thus will not 'choke the pipe 7 nor the pipe 15.

ln operation, when the tank l has been emptied the water begins to flow through the pipe 'T to refill the same. lVith the improvement however, the water does not flow directly into vthe tank but flows into the tubular casing l0. As the water flows the air is compressed inthe upper end of the chamber, and the water is forced out of the chamber through the openings 26 into the pipe l5, and into the tank. The chattering, jarring, noise, incident to the filling of tanks of this character -is absorbed by the cushion of air inthe tubular casing l0, and since the casing itself is flexible and resilient as well as the cushion, the casing absorbs a portion of the noise in question.

Since the pipe l0 is of rubber or non-con ducting material, and since this pipe is the only connection between the pipes 7 and l5, it will be obvious that no electric currents may pass over the said pipe 10, and that the said pipe will insulate the said pipes 7 and l5 from each other, thus preventing the deleterious action of such currents on the piping.

It will be observed that the pipe 10 is the sole connection between the supply pipe and the inlet pipe. rIhus the metallic continuity between the pipes is broken at the casing 10, and it is to this break in the continuity of the metal that the elimination of the chat tering, jarring noise incident to filling of the tank is due to a very considerable extent.

The cushion of air formed in thecasing or pipe l0, the flexibility and elasticity of the pipe or casing 10 and the break in continuity all combine to attain this end.

l. A device of the character specified, comprising in combination with the flushing tank, the inlet pipe thereof, and the supply pipe therefor, of a tubular casing of flexible material arranged between the supply pipe and the tank, said casing being connected at its lower end to the supply pipe with a fluid tight joint and the inlet pipe of the tank extending through the upper end of 'the casing to near the bottom thereof and having a fluid tight connection at its upper end with the casing, the lower end of the inlet piiic'beino' spaced apart from the upper cud of the supply pipe, a cap fitting over the lower end of the inlet pipe and having radial openings, the inlet pipe having openings registering therewith, and the tubular casing being of greater diameter than the inlet and supply pipes to form an annu` lar chamber between the said pipes and the casing, said fluid tight joint comprising filling nuts arranged between the ends of the casing and the inlet and supply pipes, said nuts fitting within the casing, clan'iping sleeves engaging the casing outside of each nut, the upper ends of the nuts being rccesscd, and the supply pipe extending to near the upper end of the lower end, and a packing between the upper end of the casing and the inlet pipe.
